Application filed May 16,

This invention provides certain improvements in the construction, formand arrangement of the. several parts of a belt-driven tube or conewinding machine for winding thread or the like, whereby the operation ofthe machine is facilitated, its life and efii- I .ciency materiallyincreased and its cost of production decreased.

This invention comprises a belt driven 1o winding. head including acomplete winding unit which is automatically movable to stop the windingoperation when the thread or the like is broken, or the supply isexhausted, this movement automatically relieving thedriving belt fromits stretched driving condition, permitting the belt to return to itsnormal non-stretched condition; thereby increasing its drivingefliciency and life.

This invention also comprises a manually released lever arranged toautomatically lock the winding head in its non-winding or inoperativeposition.

This invention also comprises novel means whereby the pressure on thecop being wound and the tension on the thread Or the like are .bothgradually decreased as the winding of the cop proceeds.

' lhis invention also comprises a novel steadying device for. the guidemechanism which steadying device includes a manuallyreleased steadyingcatch lever for permitting the-free outward movement/of the thread guidemechabut preventing the unintentional in- I 85 ward movement of theguide mechanism during the winding of the cop.

' This invention is equally well adapted'for either tube or cone windersby the applica tion of the proper holder and the-adjustment In the.present instance-the machine is shown as a tube I -winder, only onewinding head being shown gu and described, it being understood that themachine may include as many winding heads as desired."

The base 5 for the windinghead which includes the complete winding unit is mounted on the twoupper bars 2, 2, from which base projects the bracket 6 for holding thethread tension device.

The housing 7 of the Winding machine head is movable from its winding oroperative position to its non-winding? or opperative position. Int-hepresent instance it is pivoted at 8, about midway between its ends, tohave a limited rocking or tilting movement on the base 5. Within thishousing 7 is located the rotary cam 9, fixed to the shaft 10, which camcontrols the reciprocating movement of the thread guide 11, in the usualmanner. A spring 12, extending between the base 5 and the housing 7,tends to rock the-head to its non-winding position, when the stop motionmechanism releases the head, due to the breaking of the thread, or theexhaustion of the supply.

Thecam shaft 10 is provided-with a gear 13 which meshes with a pinion14v on the auxiliary shaft 15, which shaft is provided with a pulley 16driven by the short belt 17 from the gainer or; expansion split pulley.

18, mounted on'the cop holding spindle shaft 19. It will be understoodthat the pulley 16 is interchangeable for different ratios of wind andthat the pulley 18 may be expanded and contracted to varyits diameter,producing a gain or loss in the drive, as may be found necessary.

The means herein shown for expanding and contracting the split gainerpulley 18 to gain or lose in the wind, comprises a nut 20,screw-threaded onto the end of the spindle shaft 19, which nut isprovided with a conical ,or tapered flange 21, fitted within the splitpulley 18. The nut 20 is provided with a .knob 22 for turning the nut toex-' pand or contract the pulley. The parts are held in their adjustedposition by providing the web 23 of the nut with'an annular series ofdepressions 24 and providing the belt driven spindle shaft pulley 25with one or more spring pressed pins 26, engaging certain of saiddepressions. This spindle shaft pulley 25 is driven from the pulley 4 onthe common drive shaft 3, through the belt 27, whenthe head is in itswinding position. When the head is rocked or tilted to its non-windi n gposition, by the breaking of and stop the driving of the pulley 25 fromsaidpulley 4, through said belt. To ensure the immediate stopping of thespindle shaft pulley 25, there is provided a lever brake 28 which ispivoted to the spindle shaft housing 29 with its brake shoe resting uponthe upper end of. a vertically adjustable rod 30, in position tofrictionally engage the spindle shaft pulley 25.

The stop motion mechanism for causing the winding head to rock from itswind-- ing position to its non-winding position when the thread or thelike breaks, or the supply is exhausted, is constructed, arranged andoperates as follows:

'A rotary kicker 31, in the present instance provided with twoperipheral abutments 32, is fixed to the outer end of the cam shaft 10,exterior 'to the windinghead housing 7. A latch lever is pivoted at 33to the housing 7, the depending latch arm 34 of which lever is arrangedto be engaged with and disengaged from .the keeper 35, secured to thebase 5 for holding the head in its winding position.

T he drop wire lever is pivoted at 36 to the upper end of the arm 37 ofthe latch lever, which drop wire lever is provided with one arm 38,bearing the drop wire 39 for engaging the thread or the like, andanother arm v40 arranged to be brought into and out of engagement withone of the abutments 32 of the rotary kicker 31, as will be hereinafterexplained. This drop wire lever is also pro vided with a 'hook arm 41. Atrip pin 42 projects from the housing 7 between the arms 40 and 41 ofthe drop wire lever, which pin,-together with the. arms 40 and 41,serves not only to limit the swinging movement of the drop wire 39, butalso coacts with the 'cam surface 43 of the arm 40,-t0 swing the dropwire upwardly into-threading position when the stop motion has acted tostop the winding of the cop. A spring 44 extending between the housing 7and the arm 37 of the latch lever tends not only to swing the latchlever in a direction to bring the latch arm 34 into locking engagementwith its keeper 35, but also tends to hold the drop wire lever inposition to be'operated by the kicker when the drop wire falls becauseof the breaking its of the thread or the like, or the exhaustion of thesupply; it being understood that the arm 40 of the drop wire lever isnormally held out of the path of the rotary kicker by the engagement ofthe thread or the like with the drop wire 39.

To prevent the unintentional movement of the winding head, from itsnon-winding position to its winding position, a. manually released leveris provide for automatically locking the winding head when it rocks toits non-winding position. This lever is pivoted at 45 to.the housing,its

" upper arm 46 being developed into a handle located between projections51 and 52 on the housing and base respectively.

The guide mechanism for the thread or the like is constructed, arrangedand operated as follows:

The thread guide 11, hereinbefore referred to, isreciprocated upon theguide bar 53,

suitably mounted in the guideway 54, which guideway is provided with theusual arms 55, 56, loosely mounted on the cam shaft 10. The hub 57 ofthe guideway arm 56 is'provided with a depending cam arm 58,

the cam surface 59 of which is engaged by .a' stud or roller 60, carriedby the-arm 61 of a pressure lever pivoted at 62 on the winding headhousing. A spring 63 connects the other arm 64 of said pressure leverwith the winding head housing 7 The relative positions of. the springand lever arm 64 and the length of said arm are such that the springcauses the lever arm 61 to exert its greatest pressure on-the cam arm 58at the start of the winding operation, which pressuregradually-decreases as the size of the cop increases.

Means are provided for keeping the outward movement of, the thread guidesteady and prevent it from chattering as the cop is being built up,which means is constructed, arranged and operating as follows:

A rock shaft 65 is mounted in the guideway 54, parallel to the guide bar53, which rock shaft is provided near its outer end with a hand lever 66and near its inner end with a release arm 67 which engages the free endof a steadying catch lever 68,'which steadying lever is bifurcated to vform branches embracing a sector bar 69, concentric to the cam shaft 10add secured at 7.0, 71, to the outer end of the winding head housing 7,in the plane of its outer end wall.

This steadying catch lever 68 is providedwith a cross pin 72, arrangedto travel along the inner periphery of the sector bar 69, and the bottomof the slot formed by the bifur cations is provided with a cam surface73 arranged to travel along the outer'periphery of the sector bar 69.The relationship between the cam surface 73 and the cross pin 72 is suchthat the guideway 54 will be permitted to swing outwardly, as the cop isbeing wound, but will be prevented from swinging inwardly by the bitingaction on the sector bar 69 of the cross pin 72 and cam surface 73 ofthe steadyin'g catch lever 68.

The outer end of. this steadying catch lever 68 is fulcrumed at 74 one.projection 75 of the guideway 54-, the engagement of the release arm 67with the steadyingcatch lever being beyond the fulcrum 74 so that whenthe hand lever 66 is pressed-inwardly by the operator, the steadyingcatch lever is released from its biting engagement with thesector bar69, thus permitting the guideway to be moved inwardly.

The tension device,

hereinbefore referred to, carried by the bracket arm 6, is shown ascomprising a movable plate 76 and a fixed plate 77, which movable plateis hinged to swing into and out of engagement with the fixed plate, thefixed plate being-provided with a vertical series ofv ribs 78 and themovable plate with a vertical series of slots79,

to receivesaidv ribs. The proper graduated tension on the device isprovided by a combined spring and lever control as follows:

The movable tension plate 76 is provided with an arm 80, which arm isadjustably' connected througl a spring 81 to one of a sea lever pivotedat 84 to the base 5. This lever is providcd'with an uprising arm 85having an adjustable nut 86 threaded on one end of a connecting rod 87,the other end of which rod is, adjustably secured to'one of a series ofholes 88 in an arm 89 depending from the cover plate-90, removablysecured to the guideway arm 56.

' This lever and spring control for the movable tension plate 76eliminates a rigid con-- nection between the said movable tension plateand its pressure operating means, thereby permitting the plate to yieldwhen so required by bunches in the thread or the like, andto be freelyopened by the operator for threading without disturbing the other parts.v

From the above description it will be seen that when the winding of thecop starts with the parts in the positions shown in Fig. 7, the threador the like is holding up the drop wire 39 and is thereby holding thearm 40 out of the path of the abutments 32 on the rotating kicker 31.The spring 44 is also holding the latch lever arm 34 in lookse a ries ofholes 82 in the depending arm 83 of ing engagement with the keeper 35 onthe base, to hold the winding head in its winding position. Also thepressure lever tension spring 63 is exerting its maximum pull to holdthe guide 11 against the cop, with its maximum pressurel Also themaximum tension on the thread or the like is being exerted by the spring81, which maximum tension. is readily adjustable by the .adjust-v mentof the spring connection with the lever arm 83, the adjustable nut 86.on the outer end of the rod 87', and by the adjustment of the inner endof the rod 87 along the arm 89, of the cover plate 90 in any one of theradial series of holes 88, at a greater or lesser distance from therocking axis of the guideway.

As the cop builds up and the guideway 'of the guide 11 with the cop, thegu1deway movement is kept steady and the guideway is prevented fromchattering. The guideway is also locked against unintentional inwardmovement by the steadying mechanism hereinbefore described, whichincludes the sector bar 69 and the catch'lever 68, engaged therewith.After the cop has been completed and removed, or whenever it is sodesired, the

ley 25. At the same time the pulle 25 and the brake 28 are brought intorictional cont-act, to immediately stop the rotary movement of thepulley and thereby stop the winding operation. The position of the brake28 with .respect to the pulley 25 may be determined by the verticaladjustment of the rod 30 upon the freeend of which the brake rests.

During this movement of the winding operator may swing the guideway 54and head from its winding to its fnon-windits guide 11 inwardly, bypressing the hand lever 66 inwardly to release the steadying catch lever68 from its non-return gripping action on the sector bar 69.

During the winding of the cop, the pres sure of the guide 11 on the copis gradually lessened by the coaction and relationship of the tensionspring 63, pressure lever 61, 64 and the cam arm 58 of the guideway,whereby the upperend of thetension spring 63 is gradually brought nearerto'the axis 62 of said pressure lever'by the upward and inward movementof the pressure lever arm 64.

Also, as the cop is being wound, the tension on the thread or the likeis gradually lessened by the movement of the lever arm 89 of the coverplate 90, carried by the guideway, in a direction to lessen the tensionof the spring 81 which is connected to the arm of the movable tensionplate 76.

When the thread or the like breaks, or the supply becomes exhausted, thedrop wire 39 is released and permitted to drop sufficiently to bring thedro wire lever arm 40 into the path of the a utments 32 of the rotatingkicker 31, The kicker will then, by its engagement with the said arm 40,swing the latch lever arm 34 out of locking engagement with the keeper35 on the base 5, thereby permitting the winding head tobe rocked fromits winding to its nonwinding position. In the present instance this isaccomplished by means of the spring 12, although the pull of the drivebelt 27 is ordinarily sufiicient to rock the head to this position,without the assistance of the said spring 12.

As thewinding head is rocked to its nonwinding position, the cam face 91of the latch lever arm 34, by its engagement with the side of the keeper35, will positively swing the latch lever far enough to not only towardthe main drive pulley 4, thereby looseningthe driving belt 27, causingit to drop away from its drive pulley 4 andrendering it inefiective todrive the said puling position, the manually released lever,hereinbefore described, moves automatically either by gravity, as shown,or by any other urge, in a direction to slide the wedge 49 between theprojections 51 and 52 on the head and base respectively, to lock thehead in said non-winding position until it is intentionally released bythe movement ot the lever in the opposite direction, by the operator.-This locking arrangement of the winding head prevents the unintentionalrocking of the head to its wmdin pos1- tion and is particularlydesirable or preventing the movement of the head to restart themachinewhile the cop is being removed a from its holder.

, When it is desired to re-start the machine after the thread or thelike breaks, or its supply is exhausted," the manually released lever ismoved by the operator in a direction to withdraw the wedge 49 frombetween the abutments 51 and 52, thereby permitting the winding head tobe manually rocked back to its winding position. This movement of thehead will cause the latch lever arm 34 to engage the keeper 35 on thebase and hold the head in its winding position. When it is desired tostart the winding of a new cop, the guideway 54 andits thread guide 11are moved inwardly after manually releasing the steadying catch lever 68from the sector bar 69, this inward movement of the guideway serving toplace the maximum tension on the cop and on the thread or the like beingled thereto. The winding head is then manually rocked to its windingposition and there held, as before described.

Among the many advantages arising from the use of the movable windinghead are; the removal of strain upon the driving belt except when thebelt is in use, thereby adding materially to the life of the belt; theelimination of the usual, belt shifting mechanism'and its loose pulley;the elimination of the usual clutch mechanism which has the disadvantageof an unduly abrupt starting of the winding; and the provision of amech-= rangement of the. several parts without 'de- ,parting from thespirit and scope of, my in-.
